PUMP.

SPECIFICATION forming part of Letters Patent No. 482,588, datedSeptember 13, 1892.

Application filed April 22, 1892. Serial No. 430,230. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM PETERSON, of the township of Genesee, in thecounty of Kandiyohi and State of Minnesota, have invented a new anduseful Improvement in Pumps, of which the following is a full, clear,and exact description.

My invention relates to an improvement in pumps especially adapted foruse in tubular wells, and has for its object to construct a pump withtwo pistons actuated from a single lever reciprocated simultaneously butin opposite directions, which lever may be operated by hand or by awind-wheel or other applied power.

A further object of the invention is to provide a pump from which acontinuous stream of water may be made to flow and to construct the pumpin a simple, durable, and economic manner.

The invention consists in the novel construction and combination of theseveralparts, as will be hereinafter fully set forth, and pointed out inthe claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure l is a partial side elevation and partial vertical section of theupper portion of the pump or that portion adapted to be located abovethe platform or ground. Fig. 2 is a continuation of the pump, the saidcontinuation being shown in vertical section and representing thatportion of the pump contained between the upper platform and thewell-tubing; and Fig. 3 is a vertical section through a portion of thewell-tubing.

The body A of the pump may be made in any suitable or approved manner,but preferably consists of a shell or casting of metal, which extendssome distance above a platform 11 and some distance below the platform,as shown in Fig. 2. The upper end of the shell of the pump-body isprovided with a head 12, which carries a delivery-nozzle 13, and thepump-body is also provided with a valve-rod 14:, extending through itfrom top to bottom,the said rod having attached to its top a knob 15, towhich the valve-rod is conneoted, the said knob being adj ustablein thetop' of the pump. At the lower end of the valve-rod a valve 16 islocated. This valve is of disk form and has its periphery covered 55 bya cushion 17, of rubber or a like material, the cushion being preferablymade to extend some distance from the periphery.

The lower end of the pump body 1Q screwed or otherwise secured in anopening produced in a box 18, near one end of the upper surface of thelatter, and a second opening is made in the upper portion at theopposite end of the box, which receives the lower end of a tube 19, theupper end of this tube being closed by reason of its engagement with theplatform 11, and this tube serves the dual purpose of a support for theplatform and as a reservoir for air.

In the bottom of the box 18, immediately beneath the lower end of thepump-body, an elbow-pipe 20 is screwed or otherwise secured, and thispipe is normally closed by the valve 17 above referred to. Piping is tobe connected with the elbow leading to tanks located at any desiredpoint. Thus while the valve is seated over the elbow water will flow upto the mouth of the pump, and when the valve is screwed up to close thelower end of the body-tube 10 the water will flow through the elbow 20.The upper section 21 of the main well-tube is screwed into or otherwiseplaced in connection with the box 18 at or near its center, and thisupper tube is connected with a second strainer-section 22 of thewell-tube in any suitable or approved manner, and where the two sectionsof well-tubes unit-e a suction-valve 23 is located, the valve beingpreferably of the character known as a puppet-valve.

Within the upper section of the main welltube a tube 24 is held toslide, the lower end of which tube is provided with a plungervalve 25 oflike nature as the suction-valve 23, the valve-stem being provided withthree or more packing-rings arranged one above the other. A secondplunger-valve 26 is held to slide in the interior tube 2a, and thisupper valve is similar to the lower one. Wh n th upper valve is carrieddownwardit opens a d when it is carried upward it closes, and the lowervalve 25 has a like action. The extreme upper end of the interiorsliding tube 24.- is connected with a valve-rod 28 through 2 aaasea themedium of a spider or cage 2'7, and the plunger-valve 26 is carried by acage which has attached to it a rod 29. The rod 29 passes upward throughthe cage 27, and both rods 28 and 29 are carried upward through the box18, the latter being provided with suitable stuffing-boxes 30, andlikewise up through the platform 11 and also above the platform,preferabl y at one side of the pump-body, the upper ends of the rodsbeing guided by passing through sockets in an extension 31 of a standardor post 32, and the rods are further guided by passing throughaperatures in arms 33, projected from said standard, as shown in Fig. 1.Both of the plunger-rods are provided with the usual stops 34,1imitingtheir upward and downward movement. The rods are to be verticallyreciprocated simultaneously, but in opposite directions, the objectbeing to draw one plunger-valve upward while the other is forceddownward. This is accomplished through the medium of a series of leversand a main or handle lever 35. The handle-lever is connected indirectlywith the plunger-rod 28, the handlelever being fulcrumed upon one end ofthe arm 36, the opposite end of the arm being pivotally attached to thepost 32. Where the handle and arm 36 are pivotally connected, one end ofa bar 36 is pivotally secured, the opposite end of the rod beingfastened to the plunger-rod 28, and the inner end of the bandle-lever issecured to the bar 36 near the attachment of the latter withtheplunger-rod, as shown in dotted lines in Fig. 1. Near the center ofthe connecting-bar 36 one end of a link 37 is pivoted, and this linkextends downward, and its opposite end is pivoted to one extremity of alever 38, which is fulcrumed near its center upon the post 32. At theopposite end of the lever 38 one extremity of a longer link 39 ispivotally attached. This link extends downwardly and forwardly indirection of the plunger-rods, and at its lower end is in its turnattached to a lever 40 near the center of the latter, thisleverconsisting of a long section 4:0 and short section 40", the two beingpivotally united. The short section is pivoted to the post 32 and thelong section is attached to the plunger-rod 39. It will be observed thatby working the handlelever 35 up and down the toggle connection, whichconsists of the links 37 and 39 and the lever 38 between thehandle-lever and the lower sectional lever 40, will cause a verticalreciprocating movement of the plunger-rods; but the rods will be movedalternately in opposite directions-that is, one upward and the otherdownward. Consequently the plunger-valves attached to the rods will beoperated in the same manner, and the effect will be as follows: The pumphaving been in operation for a short time, and presuming the position ofthe plunger-valves to be that shown in Fig. 3, a column 'of water willbe maintained between the two plunger-valves. Upon the manipulation ofthe handle-lever 35 the upper plunger-valve will be forced downward inan open position, the lower plunger-valve will be carried upward in aclosed position, and the column of water between the two valves will beforced through the upper valve, While the lower valve will createsufficient suction to draw up water through the well-tube through thesuctiolrvalve, and when the upper plunger-valve is carried upward it(closing at that time) forces the column of water above it upward also,and the lower plunger-valve in passing downward closes thesuction-valve, yet opens itself, and the column of water which has risenbetween the suction-valve and the lower plunger-valve will find its wayupward through the latter, so that when next the upper plunger-valve ismoved downward and the lower plunger-valve upward a column of water willbe at hand to be forced through the upper plunger-valve by the lowerone, and this operation takes place repeatedly, the result beingthatwaterwill flow uninterruptedly through the nozzle of the pump duringthe process of pumping. The elbow valve is opened only when it isdesired to discharge water from the pump proper-as, for instance, toprevent freezing.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In a pump, the combination, with the welltube, itssuction-valve, a tube having sliding movement in the well-tube above thesuctionvalve and having its lower end provided with a plunger-valve, asecond plunger-valve having sliding movement in the sliding tube, and

plunger-rods, one connected with the sliding tube and the other with thevalve sliding in the tube, of a pump-body in connection with thewell-tube above the sliding tube and sliding valve, a standard, a handlefulcrumed upon the standard through the medium of a link and having aconnection with one of the plunger-rods, a lower lever comprising a longand a short section pivotally connected, the short section being pivotedto the post or standard and the long section attached to the otherplunger-rod, a lever fulcrumed near its center upon the post or standardbetween the upper and lower levers, a link connection between thefulcrum of the upper lever and its connection with the plunger-rod andone extremity of the intermediate lever, and a second link connectingthe opposite extremityof the intermediate lever. with the longer memberof the lower sectional lever, as and for the purpose set forth.
